Arab Weather - Have you ever asked yourself: Clouds are fluffy and soft like cotton, right? The reality is a little different. According to the United States Geological Survey, the average weight of a cloud is about 500,000 kilograms! This begs the question: How does this massive mass stay suspended in the sky without falling to the ground?

It's like you're asking me what clouds are and how they form?

Clouds are a visible form of atmospheric condensation. They form when warm air, laden with water vapor, rises in the atmosphere, as this air is lighter than the surrounding air. Wind also plays an important role in pushing the moist air upward. Condensation then begins, as the air temperature drops at higher altitudes due to lower atmospheric pressure. Water vapor then condenses into tiny droplets or ice crystals. For this to occur, tiny particles known as condensation nuclei, such as dust, smoke, and sea salt, are required to help the water vapor coalesce to form clouds.

Why don't clouds fall over our heads?

Clouds can stay suspended in the sky just like oil floats on water, because the density of oil is less than that of water. The same thing happens to warm air loaded with very small water droplets. Warm air loaded with small water droplets is less dense than dry air. This means that the cloud will not fall towards the ground, because the air beneath it is heavier. Therefore, clouds float in the sky.

What keeps the cloud warm and less dense than dry air is the constant condensation process within it. When the vapor condenses, it turns into very small water droplets inside the cloud, and heat is generated. This means that the cloud is constantly self-heating and maintaining its low density, which allows it to remain high in the sky, similar to a balloon.

Although the cloud's weight is very large, the density of the dry air beneath it keeps it floating in the sky. Therefore, we can say that clouds are a magical natural phenomenon that adds beauty to the Earth's sky, without being too heavy.
